;; $Log: todomode.el,v $
+;; Revision 1.4 1997/08/04 16:18:45 os10000
+;; Added Raise/Lower item.
+;;
;; Revision 1.3 1997/08/03 12:47:26 os10000
;; Cleaned up variables, prefix and cursor position.
;;
;; Then you have the following facilities available:
;;
;; M-x todo-mode will enter the todo list screen, here type
-;; p for the previous entry
-;; n for the next entry
-;; q to save the list and exit the buffer
+;; + to go to next category
+;; - to go to previous category
;; e to edit the current entry
+;; f to file the current entry, including a
+;; comment and timestamp
;; i to insert a new entry
;; k to kill the current entry
-;; r raise current entryk's priority
;; l lower the current entry's priority
-;; f to file the current entry, including a
-;; comment and timestamp
+;; n for the next entry
+;; p for the previous entry
+;; q to save the list and exit the buffer
+;; r raise current entryk's priority
+;; s to save the list
;;
;; I would recommend to add the following bindings to your global keymap:
;;
-;; (global-set-key "\C-ct" 'todo-mode)
+;; (global-set-key "\C-ct" 'todo-show)
;; (global-set-key "\C-ci" 'todo-cmd-inst)
;;
;; This will enable you to quickly find the todo-list, or to simply add an
;; entry, without changing to it and getting sidetracked from your current
;; project.
;;
-;; I would also recommend that you execute the command
-;;
-;; (setq todo-prefix "*/* ")
-;;
-;; to have all your entries prefixed in such a way that the diary displays
-;; them every day.
+;; I would also recommend that use the prefix "*/*" (by leaving the
+;; variable 'todo-prefix' untouched) so that the diary displays
+;; each entry every day.
